BURNER-NIPPLE PRICKER AND CLEANSER.

Specification of Letters Patent.

Patented June 16, 1908.

T 0 all whom it may concern.

Be it known that I, SAMUEL SPILLER, a subject of the King of GreatBritain and Ireland, &c., residing at Rockhampton, in the State ofQueensland, Commonwealth of Australia, have invented certain new anduseful Improvements in Burner-Nipple Prickers and Cleansers; and I dohereby declare the following to be a full, clear, and exact de scriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

The object of this invention is to provide an improved pricker andcleanser for trimming the nipples of burners as of acetylene gas andothers liable to become choked by the products of combustion. Manyburners become useless or defective in operation if not cleansed. IVirehas been used for cleaning such nipples, but this invention provides anew combination of parts for holding the cleaning member, which need notbe a wire in all cases, and for allowing of its insertion andadjustment, the whole forming a simple pocket tool. The said tool, whichhas no part adapted to be lost, is illustrated in the accompanyingdrawings, in which Figure 1 is a side elevation of the tool open,

with two wires, and with another cleaning member (which is dis ensedwith in some cases) as described be ow. Fig. 2 is a side elevation ofthe parts in Fig. 1, the tool being however closed. Fig. 3 shows theparts in Fig. 1 in plan view, in slightly modified form, and omittingthe wires. Figs. 4 and 5 show details.

In these drawings (1,?) are the two sides and c, d the two ends of asheath formed by taking a blank of sheet metal or material and bendingit on its longitudinal axis so that there is a longitudinal recess abetween the said sides which is closed on three sides. Side a projectshigher than I). The recess at end (i is wide, but at end 0 narrow.Riveted at 6 some distance from the narrow end 0 is a bar or blade fwhich may be closed or opened like the blade of a pocket knife, butwhich has no sprin Blade f may be of any suitable materia l, its outerend being provided with a wire holder formed by bending over a part 9provided in the blank from which the blade 1S made, a doubled part beingthus made. This doubled or folded portion is the wire or pin holding andadjusting means. In some cases one platinum wire simply would be used;but in Figs. 1, 2 two (i, j) are shown with long ends 2, j in reserve,these ends being bent out of the way along the blade In Fig. 4 a singlewire is shown bent to form two prickers or pins i 3' When there is scopefor using two or more pins simultaneous y, to cleanse burners arrangedin pairs, this invention is useful, as any particular distance betweenthe pins or wires is readily insured, and the part g whether folded onthe blade from the end of the latter as in Figs. 3 to 5, or from anotheredge as in Figs. 1 and 2, can be readily made tight upon any wire by aslight hammer blow. In some cases I provide a small regulating screw gpassing freely through a hole in the part g and screwing into a threadedhole in the bladef so as to insure the desired tight grip, and allow ofloosening when desiredsee Figs. 3 and 4. Screw 9 draws part g tightagainst the wire or cleaning member. When the wires are of greaterlength than the width of the blade the excess length is readily kept inreserve for use (by degrees) in each case as the cleansing end becomesworn, and needs cutting off.

In Figs. 1 and 2 holes g are shown in part g, and through these holesthe wires pass, but wire is also shown held by a folded member g, whichhas no holes; see Fig. 4.

Fig. 4 shows a loop Z in a wire which has pin points "L 3' the loopbeing for cleaning urners having slitted nipples.

In Fig. 5 a thin slit cleaning blade Z is shown secured in the foldunder member g and with its rear end Z turned over part g.

In Figs. 1 and 2 the blade end 7c is made thin to serve as a slitcleanser, the folded part being located lower on the blade. 72, is a projeetion on bladef to act as a stop to abut on side I) and prevent theblade closing so far as to damage the pins i, j, or other cleansingpart, while at the same time these parts are protected when the tool'isclosed. This will be clear from Fig. 2 in which a part of side 1)appears broken out for clearer illustration. It is important that thepricking ends of the wires may be easily regulated in length, as thebladef then acts as a stop to prevent the wires being pushed in too far,and damaging the delicate burner. The wide end of recess (1 receives thethick part of blade Pivot e is sufficiently removed from the end 0 ofthe rear side (see Fig. 1) of the sheath to allow that end to act as astop to prevent the blade being opened back too far. Fig. 1 shows thefully opened position.

The illustrations are not to be regarded as limiting this invention tothe sizes, proportions, or numbers of parts used in the construction.

What I do claim as my invention and desire to secure by Letters Patentof the United States is 1. A tool sheath, a blade pivoted thereto andadapted to be inclosed therein, said blade having a portion folded uponitself and wires held by said folded ortion.

2. A tool sheath, a blade pivoted thereto, said blade having a portionfolded upon itself, a screw for regulating the position of the foldedportion relative to the blade and wires adjustably held by said foldedportion.

blade, and a cleaning member held by the said fold as described.

4. A device of the class described comprising a blade having a portionfolded upon itself, said folded portion having holes therein andcleaning wires assing through the holes and held by said fol dedportion.

In Witness whereof I have hereunto set my hand in the presence of twowitnesses.

SAMUEL SPILLER.
